Characterizing myths of sexual aggression in the young population in Spain

Background Myths of sexual aggression have a negative influence in aggressive behavior against women, in the institutional approaches to sexual violence and in how women cope with it. The objective of this study is to describe acceptance of myths of sexual aggression in young women and men residing in Spain. Method Cross-sectional study carried out online with 2,515 women (50.2%) and men (49.8%) ages 18–35 in Spain in 2020. Information on myths was collected using the Acceptance of Modern Myths About Sexual Aggression Scale (AMMSA). We described the myths most prevalent among women and men. The variables associated with myths were identified using multiple regression. The regression models were adjusted by sociodemographic and sexual orientation variables. Results The average AMMSA values were higher among men [mean: 3.11; standard deviation (sd):1.23] than among women (mean 2.49 sd:1.11). In both sexes, the myths with greater acceptance showed the presence of patriarchal gender roles in sexual contacts. Men were more likely than women to accept myths that question allegations and severity of violence. Having a higher level of educational studies (β -0.350 sd: 0.046) was associated with lower average AMMSA values. Being born in Latin America (β 0.047 sd: 0.063) was associated with higher average AMMSA values. Among heterosexual men, AMMSA values were greater than among gay and bisexual men. Among women, there was no difference in average AMMSA values based on sexual orientation. Conclusions Myths persist during youth that question and trivialize sexual violence against women. It is necessary to implement strategies that reduce these myths, particularly in heterosexual men, in those of foreign-born origin and among those with low levels of education.

Background
Sexual violence (SV) encompasses any act, attempt or action against a person's sexuality using coercion, regardless of their relationship to the victim [1].SV is a violation of human rights that threaten freedom, dignity, security, and the right to life.They primarily affect women and girls and are perpetrated almost exclusively by men [2].
Prevention of SV is a public health priority, due to its magnitude, negative impact on mental and physical health and structural nature [3].It is estimated that 11% of women in the European Union have suffered SV at some point since 15 years of age [4].In Spain in 2019, 13.7% of women over age 16 reported having suffered SV at some point in life, and SV was more frequent among women ages 18-24 (19.1%) [5].
Despite its high prevalence, seeking help in situations of violence against women is scarce.Recent studies carried out in Spain show that young adult women who suffer intimate partner sexual violence are the least likely to report these events to formal services (social services, health services, community services) [6] Reporting of sexual crimes to police is still infrequent.In the EU-28 it is estimated that 15% of women that experience SV declare this aggression to the police [4].In Spain, an estimated 8% of women that have suffered from SV outside of an intimate partnership reported these incidents [5].There are also a scarce number of convictions for sexual crimes among cases [7,8].Studies link this low frequency of reports of sexual violence and small number of convictions to the social acceptance of rape myths [9,10].
Rape myths are a set of beliefs that create a cognitive schema guiding the interpretation of information and events that occur in a sexual assault.The concept was originally defined by Burt [11] and refined by Bohner in 1998, and refers to a set of "descriptive or prescriptive beliefs about rape (that is, about its causes, context, consequences, perpetrators, victims, and their interaction) that serve to deny, belittle, or justify sexual violence by men against women." [12].Research on rape myths has traditionally focused on sexual assaults of extreme violence [13], leading to estimates possibly biased by social desirability.
Subsequently, Gerger and collaborators [14] developed the Scale of Acceptance of Modern Myths about Sexual Aggression (AMMSA), which gathers perceptions about a wider range of sexual assaults [15].AMMSA has been validated in Spain by Megias and collaborators among students from the University of Granada (Spain), proving to be a useful tool for the analysis of social perception regarding sexual assaults [15].
Studies on Myths of Sexual Aggression suggest they have a negative influence on aggressive behavior [16,17] institutional approaches to sexual violence (VS) [18], recognition of VS [19], and how women cope with it [20].
Given the high prevalence of VS among young women in Spain, the aim of this study is to characterize the level of acceptance of myths about sexual aggression among young men and women residing in Spain, in the year 2020.

Population and sample
Cross-sectional study based on the online survey "Sexual Violence Among Young People", carried out with women and men ages 18-35 residing in Spain (see additional file questionnaire).The sample size calculation was carried out taking into account recent data on the prevalence of SV in Spain, obtained from the Macrosurvey on Violence Against Women [5], corrected for sex.Data on the Spanish population ages 18-35 were obtained from the National Statistics Institute [21].A minimum sample size was calculated of 2,500 questionnaires, to ensure a sample error of ± 5%, considering a 95% confidence level and prevalence estimates with a precision of (+/-) 0.9.In order to ensure that the sample was representative of the young population residing in Spain, quotas for sex, age, and autonomous community were applied.The participating individuals were selected from an online panel of 138,393 adults aged 16 and older.The panel was representative of the non-institutionalized civilian Spanish population.Participants were recruited via email and those who accepted received a link to respond to the survey.After conducting a pilot study, a database with 2,515 records collected between September 30 and October 28, 2020, was obtained.The response rate was 63.2%.Participation required the signing of a signed informed consent.The study was conducted according to the guidelines of the Declaration of Helsinki and was approved by the Ethics Committee of the University of Alicante (ref. UA-2020-07-07).

Dependent variable
The measurement of the acceptance of myths about sexual aggression was conducted using the Acceptance of Modern Myths about Sexual Aggression Scale (AMMSA) [15], which consists of 30 items.These items form a single construct that covers the following categories: (a) denial of the problem; (b) questioning the intentions of the women who report; (c) critical position regarding the support provided to women by public policies; (d) naturalization of the lack of male sexual control; (e) beliefs that blame the victim, the circumstances and justify the aggressor's behavior.The items are straightforward and are answered on a 7-point Likert scale (range: 1-7).Higher values indicate greater acceptance of myths about sexual aggression.In our study, the scale showed high internal consistency (α = 0.95), with values similar to those obtained in its validation (α = 0.91) [15].

Analysis
First, we described the sample, globally and stratified by sex, according to the abovementioned covariables.Later we described the average AMMSA values by covariable categories.The differences in average AMMSA values between categories of covariables was carried out using the Student t-test for dichotomous variables and using the ANOVA in the case of variables with more categories.Later we described the average values of the items with greater or lesser acceptance, in the total sample and stratified by sex, as well as the items with the greatest and least differences between women and men.The difference in the average values for each item between men and women (difference = men's average -women's average) was analyzed using the ANOVA test.Finally, we analyzed the relationship between the AMMSA factor and the covariables using multiple regression analysis.In a prior step, analyses of residuals were carried out in order to verify that they were homoscedastic and that there was no multicollinearity.We explored interactions between the variable sex and the rest of the included covariables in the model and identified an interaction between sex and sexual orientation.

Results
The database analyzed included 2,515 entries, of which 50.2% were women and 49.8% were men.Table 1 describes the characteristics of the total sample and the sample stratified by sex.
Table 2 shows the average AMMSA values based on the covariable categories.AMMSA had an average value per item of 2.80 and a standard deviation (sd) of 1.21.The average AMMSA values were significantly greater in men [3.11( 2).Table 3 shows the AMMSA scale items that obtained the most extreme scores.The average score for all of the items of the AMMSA scale can be found in the additional material [see Additional file 1].For all of the items the average score was significantly greater in men than in women.Among both sexes the items that obtained the higher scores were item-19, which criticizes the opportunistic use of SV in politics and the media, and item-1, which shows traditional roles in sexual contacts.Next, there are the items critical of the support women who are victims of sexual aggression receive (item-25).
The items that had lower scores in both sexes were those that directly blame women or their circumstances (item-11), items that consider the penalties for the aggressors to be appropriate (item-30) and items that question rape in a relationship (item-17).
The greatest differences between women and men, with higher values in men (Table 4) were for items that refer to the incorrect interpretation of men's behavior (item-5), items that refer to women's exaggeration of SV (items-27, 16, 23) and the use of false accusations of SV to obtain legal benefits.Also observed among men was a more critical position in terms of the severity of SV in society (item-29).The highest degree of consensus between women and men (Table 4) was found in items with low acceptance among both sexes, such as those that exonerate the aggressor (Table 4).
Table 5 shows the variables associated with acceptance of myths of sexual aggression.The average acceptance of myths of sexual aggression was lower in people with a higher level of education -reference: up to secondary studies-(β:-0.350sd: 0.046).The average value of AMMSA was higher in people born in Latin Americareference: Spain -(β:0.250sd: 0.063) (Table 5).
An interaction was identified between sexual orientation and sex (Fig. 1).In heterosexual men average AMMSA values were higher than in gaysexual/bisexual men.For women there was no difference in the average AMMSA values by sexual orientation.

Discusion
The acceptance of myths of sexual aggression was greater in men than in women.Among both sexes, the myths with greater acceptance refer to the presence of patriarchal gender roles in sexual contacts and to the opportunistic use of SV in politics and in the media.There are myths that maintain a critical stance towards institutional support for victims.Men had greater acceptance than women of myths that question reporting of SV or trivialize the severity of SV.Being a heterosexual man, lacking a higher level of education and being born in Latin America was associated with a greater acceptance of myths of sexual aggression.
Average acceptance of myths of sexual aggression found in this work was less than what was identified by Mejías and colleagues in 2011 [15] with a sample of university students.This result could suggest a decrease in the acceptance of myths of sexual aggression in the past decade, primarily among women.This fact could be related to a greater level of awareness and more critical social stance towards SV in Spain, in part prompted by the influence of cases of SV with a high level of media attention among the young population and by worldwide women's social movements such as #MeToo2017 and #YoSiTeCreo-2018 [23].
Despite this possible decrease in the acceptance of myths of sexual aggression, in the young population, myths persist that reflect patriarchal gender roles in sexual contacts and that question SV and the institutional response to the problem.This negation, trivialization of SV and questioning of reporting, observed primarily among men, has important implications both in terms of  victim's request for help [10,13] and in the victim's recuperation of wellbeing [24] as well as in the response of SV support services [9,25].Prior studies show that the probability of a woman seeking help decreases when she perceives that her testimony could be questioned [10].At the same time, other studies have identified an association between the acceptance of myths of sexual aggression by professionals in the police and judicial services and secondary victimization of women who suffer from SVcalled "judicial rape" [26].This secondary victimization related to the lack of credibility in women's testimonies has been associated with the withdrawal of complaints [18], which can also serve to strengthen the myth of false complaints.
In this study, myths that had a lower level of acceptance among both sexes were those that blame the victim and that do not recognize SV in a couple relationship.This result does not agree with what has been observed in qualitative studies of young people, carried out in England and Wales [27] and in United States of America [28], in which discourses have emerged that blame the victims [27,28].The distinct methodological approach, as well as the possible social desirability bias present in our work related to the more extreme items could explain these differences [14].
There was also a greater acceptance in men than in women of myths that question situations of assault.This result could be a reflection of men's normalization of sexual assault, an important point given the high prevalence of assault both in Spain and in the European context [4,5,29] and its impact on women's health and wellbeing [30].In this sense, the new Organic Law on Sexual Liberty [31] has defined street harassment of a sexual nature as a crime.
Our results show an associate between the acceptance of myths of sexual aggression and the sociodemographic characteristics of young people.Specifically, we observed a greater acceptance of myths of sexual aggression in those with a lower level of education, those born in Latin America and in heterosexual men.Although information on the association between myths of sexual aggression and sociodemographic variables of young people is scarce [16], the acceptance of myths of sexual aggression has shown a high correlation with scales that measure social constructs of hostility towards women, such as ambivalent sexism [32].Having a low education level  has been associated with myths acceptance in our work, and it has also been associated with higher average levels of ambivalent sexism in both sexes [33].In terms of place of origin, to our knowledge, there are no prior studies that analyze the association between migratory status and acceptance of myths of sexual aggression.Although scarce, there are studies conducted in England and Wales that identify a positive association between belonging to an ethnic minority and acceptance of these myths [27].
It is necessary to carry out more studies that analyze the reasons underlying these associations and avoid the stigmatization of social groups in which different axes of inequality intersect.
One novel finding of our study is the association between sexual orientation and acceptance of myths of sexual aggression, an association modified by sex.Heterosexual men showed a greater acceptance of myths of sexual aggression than gay/bisexual men.It is possible that ambivalent sexism, primarily in the dimension of hostile sexism, which is more present among heterosexual men than among gay/bisexual men, could partly explain this association [34,35].In our work, there was no association between sexual orientation and acceptance of myths of sexual aggression in women.Also, no association between sexual orientation and hostile sexism has been identified in women [36].
This study should be interpreted taking into account its limitations and strengths.Although the sample in this study was not randomly selected, the sample size and representativeness of the sample were designed to maximize external validity.In terms of the scale used -AMMSA-, it is possible that the items that refer to more serious behaviors could be subject to social desirability bias.We were not able to analyze the categories that make up the sexual orientation variable independently in the regression model due to the small number of cases in some categories.Due to the composition of the panel used, the immigrant population included in this work was exclusively of Latin American origin.Even though we were unable to extrapolate the results to other foreign origin groups, it provides information on an immigrant group from a single region of origin.Despite these limitations, our results provide new information on an understudied topic which is currently of great importance.

Conclusions
Myths of sexual aggression persist among the young population in Spain and are more present among men than among women.Greater differences by sex were found for myths that question and trivialize SV suffered by women, and these were more accepted by men.Sociodemographic variables were associated with sexual aggression myths independently of sex, while the association between sexual orientation and these myths differed between men and women.It is necessary to implement public policies that reduce the acceptance of myths about sexual assaults in the Spanish population.These policies should have a comprehensive approach, incorporating the different axes of inequality that converge in the population.
